This isn't really what I was talking about either. This is the only wormhole I could find on short notice, but it's disturbed (the pulsating effect you see), and it isn't large enough for me to orbit it at the threshold. Never the less, I thought you might like it. Maybe next time I find the right one, I'll remember to make a video. http://wwuzone.com/bitbin/wh.wmv
The effect I wanted to show was the extreme distortion of space on both sides, but you can't really see this through the pulsing.
